Overview
The Crown Automotive 3175779 is a Dana 35 crush sleeve for the rear axle. The crush sleeve sets the pinion bearing preload when the pinion is installed, so it is a required spacer in the axle assembly. The axle location is front and rear and the axle type is Dana 30 reverse, which differs from the Dana 35 in the title, so confirm the axle before ordering.
It is a direct fit for several Jeep models and is part of Crown Automotive’s Jeep replacement range. The part number is 3175779.
Key features
- Dana 35 crush sleeve
- Rear position, direct fit
- The axle location is front and rear.
- The axle type is Dana 30 reverse.
Setting pinion preload
A crush sleeve sits between the pinion bearings and is compressed to a set preload when the pinion nut is tightened. Because the sleeve crushes, it is installed once and the preload is then set with the bearings, rather than adjusted afterward. The sleeve length must suit the axle, so compare it with the old sleeve before the pinion is set.
Work slowly when tightening the pinion nut and check the rotating torque at intervals. A preload that is too high can damage the bearings, and one that is too low can allow play in the pinion. Keep the pinion, yoke and bearing races clean and free of burrs before assembly.
- Compare the new sleeve length with the old sleeve
- Tighten the pinion nut in small steps
- Check rotating torque at intervals

Installation notes
A crush sleeve is tightened to a set preload on the pinion, so the sleeve is installed once and the preload is set with the bearings. Check the crush sleeve length against the axle before the pinion is set, since a sleeve that does not match will change the bearing preload.
What’s included
